However, the antenna implemented in the electronic device 200 of FIG. 2 and/or an antenna implemented in an electronic device to be mentioned after FIG. 2 may not be limited to corresponding to the communication module 120 of the electronic device 100 of FIG. 1. For example, an antenna according to various embodiments of the present disclosure may be extensively applied to various communication fields that will be developed in the future.

FIG. 2 is a block diagram of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 2, an electronic device 200 is illustrated, where the electronic device 200 may include a control signal generation unit 210, a signal transmission unit 220, a signal processing unit 230, a ground connection unit 240, and a communication signal generation unit 250. However, the electronic device 200 shown in FIG. 2 is just one embodiment of the present disclosure and its several modifications are possible based on components shown in FIG. 2. For example, the electronic device 200 may further include a user interface for receiving some instructions or information from a user. In this case, the user interface may be an input device such as a keyboard and a mouse in general but may be a graphical user interface (GUI) displayed on an image display device.

The control signal generation unit 210 may generate a control signal corresponding to a user input. At this point, the user input may relate to a manipulation of a volume button or a power button of the electronic device 200. For example, when a user presses (or, click, touch or activate) a volume down button to reduce the volume of a video being played by the electronic device 200, the control signal generation unit 210 may generate a control signal for requesting the volume down. Similarly, when the user presses a power button for activating the electronic device 200, the control signal generation unit 210 may generate a control signal corresponding thereto.

The volume button or the power button may be disposed at a side of the electronic device 200.

However, the user input is not limited to a button equipped at the side and extends to a physical button disposed at another portion of the electronic device 200. For example, a volume button or a home button may be disposed at the front or the rear of the electronic device 200.

Further, the user input may be input via a sensor (for example, the sensor included in the sensor module 140 of FIG. 1) mounted at the electronic device 200 in addition to the physical button of the electronic device 200. For example, when a proximity sensor (for example, the proximity sensor 140G of FIG. 1) of the electronic device 200 detects that an arbitrary object (for example, a user's finger or face) approaches the electronic device 200, the control signal generation unit 210 may generate a control signal for notifying this.

The signal transmission unit 220 may transmit the control signal generated by the control signal generation unit 210 to the signal processing unit 230. According to various embodiments of the present disclosure, the signal transmission unit 220 may include a printed circuit board (PCB), a Flexible PCB (FPCB), or a conductive material.

According to various embodiments of the present disclosure, the signal transmission unit 220 may include a signal line and/or a ground plate of the PCB, the FPCB, or the conductive material.

The signal line is a line that mutually connects the control signal generation unit 210 and the signal processing unit 230, wherein one end of the signal line may be formed on a ground plate of the signal transmission unit 220 and the other end of the signal line may be formed on a ground plate of the signal processing unit 230. For example, the signal line may connect the control signal generation unit 210 and the signal processing unit 230, crossing over the ground plate of the signal transmission unit 220 and the ground plate of the signal processing unit 230.

The signal line may include an inductor and/or an RF choke (RFC). The inductor and/or RFC may be electrically shorted in direct current (DC) or low frequency and may be electrically open in high frequency.

In various embodiments of the present disclosure, since a control signal generated by the control signal generation unit 210 is of DC or low frequency, the signal line may be shorted and the control signal may be transmitted from the control signal generation unit 210 to the signal processing unit 230 through the shorted signal line.

On the contrary, since a communication signal generated by the communication signal generation unit 250 is of high frequency, the inductor and/or RFC may be open. In this case, it is same as that the signal line between the control signal generation unit 210 and the signal processing unit 230 is disconnected so that it may not deliver the communication signal.

The signal processing unit 230 may process the control signal generated by the control signal generation unit 210 and then received through the signal transmission unit 220. The signal processing unit 230 may reduce the volume of a video being played in the electronic device 200 in response to the above-mentioned control signal requesting volume down.

The ground connection unit 240 may mutually connect the ground plate of the signal transmission unit 220 and the ground plate of the signal processing unit 230. The ground plate of the signal transmission unit 220 may be described as the ground plate of the control signal generation unit 210. At this point, the ground plate of the signal transmission unit 220 and the ground plate of the signal processing unit 230 may be spaced apart from each other and may be connected through only the ground connection unit 240. In this case, the electronic device 200 may utilize the broad ground plate of the signal transmission unit 220 corresponding to the button separated from the ground plate of the signal processing unit 230 as a radiator. Therefore, according to various embodiments of the present disclosure, the volume for the radiator may be obtained easily and also, it is possible to implement a low-priced antenna without an additional implementation and a complex design of an antenna.

According to various embodiments of the present disclosure, the ground connection unit 240 may be shorted always but according to another embodiment, the ground connection unit 240 may include an inductor and/or an RFC similarly to the signal line. That is, in this case, the ground connection unit 240 is shorted when the control signal is generated, and is opened when the communication signal is generated.

Additionally, an appropriate position of the ground connection unit 240 may be determined according to the radial of the ground plate of the signal transmission unit 220 that is to be utilized as an antenna.

The communication signal generation unit 250 may generate the communication signal in order to perform communication by using a configuration of the electronic device 200. Furthermore, the electronic device 200 may further include a communication line (not shown) that mutually connects the communication signal generation unit 250 and the ground plate of the signal transmission unit 220.

The communication line may include a matching circuit. Accordingly, the communication line may be open in DC or low frequency and may be shorted in high frequency based on a frequency characteristic of the matching circuit. According to various embodiments of the present disclosure, since a communication signal generated by the communication signal generation unit 250 is of high frequency, it may short the communication line. On the contrary, as mentioned above, since a control signal generated by the control signal generation unit 210 is of DC or low frequency, it may open the communication line.

In various embodiments of the present disclosure, the communication line, as a matching circuit, may include a tunable or switch device in addition to a simple lumped device.

It is apparent to those skilled in the art that the signal generation unit 210, the signal transmission unit 220, the signal processing unit 230, the ground connection unit 240, and the communication signal generation unit 250 are implemented separately or at least one of them is integrated and implemented.

Hereinafter, the role of the above-mentioned configuration of the electronic device 200 will be described in more detail by using various internal configurations of the electronic device 200.

FIG. 3A is an internal configuration of an electronic device according to the related art.

Referring to FIG. 3A, an electronic device 310 of the related art is illustrated, where the electronic device 310 may include a power button 311, a ground plate 312, a signal line 313, and a signal processing unit (e.g., an IC) 314.

Herein, the ground plate 312 may be one ground plate and two ground plates attached to each other. Additionally, since the signal line 313 does not include an additional inductor or RFC, it may short the power button 311 and the signal processing unit 314, while being shorted regardless of a high frequency communication signal.

Additionally, various kinds of patterns (for example, a printed circuit) necessary for implementing a function of the electronic device 310 may be printed on the ground plate 312. However, in order to prevent the present disclosure from being limited by including such various patterns in the drawings shown in FIGS. 3A to 7B to be described below, the various patterns corresponding to various embodiments of the present disclosure will be displayed as slashes on FIGS. 3A to 7B.

FIG. 3B is an internal diagram of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 3B, an electronic device 320 is illustrated, where the electronic device 320 may include an area 3200, a power button 321, a ground plate 322 of a signal transmission unit, a ground plate 323 of a signal processing unit, a signal line 324, a signal processing unit (e.g., an IC) 325, a ground connection unit 326, a communication signal generation unit 327, a communication line 328, and a fill-cut area 329.

FIG. 3C is an internal diagram of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 3C, an electronic device 330 is illustrated, where the electronic device 330 may include an area 3300, a power button 331, a ground plate 332 of a signal transmission unit, a ground plate 333 of a signal processing unit, a signal line 334, a signal processing unit (e.g., an IC) 335, a ground connection unit 336, a communication signal generation unit 337, a communication line 338, and a fill-cut area 339.

Unlike the electronic device 310 of the related art, the electronic device 320 of FIG. 3B includes two spaced ground plates (for example, the ground plate 322 of the signal transmission unit and the ground plate 323 of the signal processing unit) rather than one ground plate. The spaced ground plates 322 and 323 may be separated with the fill-cut area 329 therebetween.

Furthermore, the area 3200 may be an empty space between a housing of the electronic device 320 and a substrate (for example, the ground plate 322 of the signal transmission unit, the ground plate 323 of the signal processing unit, and the fill-cut area 329) inside the electronic device 320. However, the area 3200 is not limited to the empty space and according to various embodiments of the present disclosure, the area 3200 may be an FPCB without a ground area.

Furthermore, the volume of the empty space in the area 3200 may vary according to the form of the ground plate 322 of the signal transmission unit. For example, when the ground plate 322 of the signal transmission unit is an FPCB with flexibility, the volume of the area 3200 may be reduced due to the folding of the ground plate 322 of the signal transmission unit.

Additionally, unlike the electronic device 310 of the related art, the electronic device 320 may include the signal line 324 and ground connection unit 326 including an inductor or an RFC and may include an additional communication signal generation unit 327 and communication line 328 including a matching circuit.

Unlike the electronic device 320 of FIG. 3B, the electronic device 330 of FIG. 3C does not include an additional inductor or RFC in the ground connection unit 336. Since the other configurations correspond to those of the electronic device 320, redundancy descriptions are omitted.

Hereinafter, operations of the electronic device 310 of the related art, the electronic device 320, and the electronic device 330 will be described with reference to FIGS. 4A to 4C.

FIG. 4A is a view illustrating a flow of a control signal generated by an electronic device according to an embodiment of the present disclosure.

As described with reference to FIG. 2, since a control signal is of DC or low frequency, it may short an inductor or an RFC, and may open a matching circuit. Similarly, since a communication signal is of high frequency, it may open an inductor or an RFC, and may short a matching circuit. With this in mind, FIGS. 4A to 4C will be described.

Referring to FIG. 4A a flow of a control signal in the electronic device 320 of FIG. 3B is illustrated, where the signal line 324 and the ground connection unit 326 of the electronic device 320 may be shorted. Accordingly, the control signal may be transmitted from the power button 321 to the signal processing unit (e.g., the IC) 325 through the signal line 324 and the ground connection unit 326 may be grounded. On the contrary, since the communication line 328 is open, it may not pass the communication signal.

According to another embodiment of the present disclosure, in the case of the electronic device 330 of FIG. 3C, since the ground connection unit 336 does not include an additional inductor or RFC, it may be shorted regardless of the control signal.

FIG. 4B is a view illustrating a flow of a communication signal generated in an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 4B a flow of a communication signal in the electronic device 320 of FIG. 3B is illustrated, where the signal line 324 and the ground connection unit 326 of the electronic device 320 may be opened not to pass a signal. On the contrary, the communication line 328 may be shorted thereby transmitting the communication signal generated by the communication signal generation unit 327 from the communication signal generation unit 327 to the ground plate 322 of a signal transmission unit. An area 402 on the ground plate 322 of the signal transmission unit of FIG. 4B may be an example of an area used as a radiator.

An antenna implemented in FIG. 4B may operate as a folded mono pole antenna in which the end part of the ground plate 322 of the signal transmission unit is folded.

FIG. 4C is a view illustrating a flow of a communication signal generated in an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 4C, an electronic device 330 is illustrated, where the electronic device includes a signal line 334 and a power button 331, and where FIG. 4C may correspond to the embodiment of FIG. 4B except that a ground connection unit 336 is shorted. Accordingly, a communication line 338 may deliver a communication signal generated by a communication signal generation unit 337 from the communication signal generation unit 337 to a ground plate 332 of a signal transmission unit, and in this case, an area 404 on the ground plate 332 of the signal transmission unit may be one example of an area used as a radiator.

An antenna implemented in FIG. 4C may contact a ground plate 333 of signal processing unit (e.g., an IC) 335 to operate as a planar inverted f antenna (PIFA).

According to various embodiments of the present disclosure, in order for the design of a multi-band antenna, the electronic devices 320 and 330 may additionally implement at least one radiator according to a necessary frequency band, thereby forming a multi-resonant antenna.

FIGS. 5A and 5B illustrate internal diagrams of an electronic device and illustrate flows of a communication signal generated by the electronic device according to various embodiments of the present disclosure.

Referring to FIG. 5A, an electronic device 500 is illustrated, such that in comparison to the electronic device 320 of FIG. 3B, the electronic device 500 may further include a ground plate 507 in addition to the ground plate of the signal transmission unit and the ground plate of the signal processing unit. Further, FIG. 5A illustrates a power button 501, a signal line 502, a ground connection line 504, a communication line 506 which is connected to a communication signal generation unit 505, and a signal processing unit (e.g., an IC) 503.

Referring to FIG. 5B, an electronic device 500 is illustrated which relates to a flow of a communication signal therein. The electronic device 500 includes a signal line 502 and a ground connection line 504 including an inductor or an RFC, which are opened, and a communication line 506 that may be shorted in correspondence to the communication signal of high frequency. Accordingly, the electronic device 500 may transmit the communication signal generated by a communication signal generation unit 505 to each of a ground plate of a signal transmission unit and a ground plate 507 through the communication line 506.

In this case, an area 512 on the ground plate of the signal transmission unit and an area 514 on the additional ground plate 507 may respectively serve as a radiator. In this case, since the electronic device 500 includes two radiators, it may implement a dual-band antenna. The electronic device also includes a power button 501 and a signal processing unit (e.g., an IC) 503.

The electronic devices 320, 330, and 500 are described with reference to FIGS. 3A to 5B as various embodiments of the present disclosure for the power button.

In this case, a signal transmission unit may include one ground plate and at least a part of the first signal line 604 and the second signal line 605 may be formed on one ground plate included in the signal transmission unit.

However, according to another embodiment of the present disclosure, at least a part of the first signal line 604 and the second signal line 605 may be formed on respective ground plates and the respective ground plates where the first signal line 604 and the second signal line 605 are formed may be coupled to each other.

Referring to FIG. 6B, an electronic device 600 is illustrated, which relates to a flow of a communication signal therein. The electronic device 600 includes a first signal line 604, a second signal line 605, and a ground connection line 606 including an inductor or an RFC, which are opened and a communication line 608 that may be shorted in correspondence to the communication signal of a high frequency. Accordingly, the electronic device 600 may transmit a communication signal generated by a communication signal generation unit 607 from the communication signal generation unit 607 to a ground plate of a signal transmission unit through the communication line 608. In this case, the communication signal may be divided, and each divided communication signal may be transmitted to an area 612, which corresponds to a first volume button 601, of the ground plate of the signal transmission unit, and to an area 614, which corresponds to a second volume button 602, of the ground plate of the signal transmission unit.

In this case, the area 612 corresponding to the first volume button 601 and the area 614 corresponding to the second volume button 602, on the ground plate of the signal transmission unit, may respectively serve as a radiator. In this case, since the electronic device 600 includes two radiators, it may implement a dual-band antenna.

Further, the electronic device 600 may include a signal processing unit (e.g., an IC) 603.

Hereinafter, a method of implementing a tri-band antenna will be described with reference to FIGS. 7A and 7B.

Accordingly, the electronic device 700 may transmit the communication signal generated by a communication signal generation unit 707 to each of the ground plates of the signal transmission unit and a ground plate 709 through the communication line 708. In this case, the communication signal may be divided, and the each divided communication signal may be transmitted to an area 712, which corresponds to a first volume button 701, of the ground plate of the signal transmission unit, and to an area 714, which corresponds to a second volume button 702, of the ground plate of the signal transmission unit.

In this case, each of the area 712 corresponding to the first volume button 701 and the area 714 corresponding to the second volume button 702, on the ground plate of the signal transmission unit, and an area 716 on the additional ground plate 709 may respectively serve as a radiator. In this case, since the electronic device 700 includes three radiators, it may implement a tri-band antenna.

Further, the electronic device 700 of FIG. 7B may include a signal processing unit (e.g., an IC) 703.

FIG. 8 is a flowchart illustrating a communication method of an electronic device according to an embodiment of the present disclosure.

Referring to FIG. 8, a flowchart is illustrated, such that in operation 801, a control signal generation unit of an electronic device may generate a control signal corresponding to a user input.
